Abstract

The invention discloses a red ink capable of developing for multiple times and a decoloring agent thereof. The red ink comprises, by weight, 0.1-1% of pigments, 0.01-0.1% of a regulator, 0.01-3% of adispersing agent, 0.01-1% of a connecting material, 0.2-5% of a plasticizer, 0.001-2% of a preservative, 0.2-5% of ethanol and 82.9-99.469% of distilled water. The ink has the advantages that the effect of color restoration can be achieved, and the effect can achieve the effect of periodically reminding in daily life.

Description

technical field [0001] The invention belongs to the field of stationery, in particular to ink and its fading solution, red ink and its erasing solution for writing, drawing or marking. Background technique [0002] At present, more inks have been used in daily learning and work to outline key content, but their functions are relatively single. For example, CN02142480.2 discloses a "fluorescent marking colorant and pen", that is, a fluorescent colorant used to mark objects, and CN201510914368 discloses "a waterproof ink", whose color is relatively stable during use. However, this type of ink has a single purpose during use, and it is difficult to meet the needs of different usage situations. [0003] CN2017110330652 discloses a "thermochromic ink and its preparation method", which can be applied to various temperature indicating devices in the industrial field. CN201410037404 discloses a "thermal elimination ink", which is mainly used for marking in the textile process. Th...
